Motivation and willpower are not universal and everlasting. They are finite resources we use up. And I do, every day. When I’m not full of meetings, I may be flush out of gumption at 10:00 AM, but that’s no problem if I started writing at 6:30.
Because I know myself, I know the dip is coming. It comes sooner or later, and goes deeper or shallower, depending on the day. It’s not a problem to solve, nor a weakness to overcome. It’s just the truth. I want to give in and waste time. Most often, I simply listen to that feeling and acknowledge it, then choose something easier until I can kick it into gear again.
